The invention relates to a filtration structure of particles-loaded gases of the honeycomb type and comprising a set of longitudinal adjacent channels 20 with mutually parallel axes separated by porous filtering walls, in which: each channel the outlet has a common wall with six inlet channels, each common wall constituting one side of said outlet channel, each outlet channel consists of six sides of substantially identical width, so as to form a substantially hexagonal section channel; and regular, at least two adjacent sides of each input channel have a different width, at least two input channels, sharing a wall with a same output channel, share with each other a common wall of width b and in which the ratio of the widths b / a is equal to 1 |
